ISLAMABAD: Federal Minister for Information, Broadcasting and National Heritage Senator Pervaiz Rashid said Sunday that Imran Khan's politics had degenerated from 'Minar-e-Pakistan' to the Doongi Ground in Lahore within two years. "Popularity graph of Pakistan Tehreek-e-Insaf (PTI) has declined sharply since 2013 when Imran Khan held a public meeting at the Minar-e-Pakistan," he said.
